Short answer: the KRK S12.4. It ranks #28 of 212 subwoofers by sound quality, rated 3.9/5, at $649; the SVS PB-1000 PRO ranks #51, rated 3.8/5, and costs $849, which makes this an easy call rather than a real tradeoff.
The case for the KRK S12.4: A 12 inch studio subwoofer built to pair with desk monitors, with a selectable crossover and a footswitch for quick mix checks. Watch for: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
What the SVS PB-1000 PRO does well: A ported 12 inch subwoofer with deep, room shaking bass for the money and app control. The catch: An SPL-style presentation with a heavier tone that is a little more in your face and can crush fine detail compared with Rythmik’s servo subs.
Buy the KRK S12.4. It is rated higher for sound quality than the SVS PB-1000 PRO and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
About the ratings: the KRK S12.4’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.7 to 4.1, so this verdict could change once it is measured.
